Philco 90 Oscillator question
#1

Hi fellas - It's about 1 year since I electronically restored my Philco 90.  Although it was working great for the most part, occasionally the channels would disappear for a minute or two only to return shortly afterwards.  Since I had to rewind a broken coil originally I wondered if another had a bad connection so I removed the oscillator coil.  The inner coil (34Guage) looked immaculate.  The outside had some corrosion so I removed and rewound the same direction and number of turns with 34 Gauge.  However, the wire looked thicker than gauge.  I also found 1 resistor 50% over tolerance so I replaced and rechecked all resistors which weren't originally replaced (only 4).  Afterwards, I turned it on expecting to give it a mild adjustment but it has a lot of static and the channels come and go.  I'm assuming it's not oscillating.  Any advice on the gauge and proper tuning would be greatly appreciated.  Thanks-
Mark
